Beschreibung
Zusammenfassung:	An optical scanner wherein the image of a straight line is focused by an optical element such as a concave mirror or converging lens on the arc of a circle which is scanned by a rotating drum having one or more field stops such as pin holes or optical fibers directing light upon a stationary photodetector. The optical center of the focussing element is disposed in the plane of the scanning circle; and the axis of rotation of the drum orthogonally intersects the plane at a point displaced from the optical center.
